There are problems that could be reported with the Product Link system but the problems are not caused by the Product Link system. The problem can be described as the diagnostic information or events are not received at the office. This section contains steps that are used to determine the possible cause. Check for active diagnostic codes for the Product Link. Correct any diagnostic codes before proceeding. The following items should be visually inspected for damage: PL121SR radio, PL300 module, antenna and cables. Verify that there are no loose connections.The Product Link system depends on several communication links in order to transfer data from the machine to the office. The following procedures assume that these communication links are operating properly. The proper communication links are listed below:
The satellite network for VHF communications is operational in the geographic area of concern. The network is operational when messages can travel to the satellite and the messages can travel to the earth and Caterpillar.
The Product Link system is correctly configured to communicate on the network for VHF communications.
The worldwide network of Caterpillar's computers is passing messages to software of the Caterpillar Equipmentmanager (EM).
The Caterpillar Electronic Technician (Cat ET) is configured properly and the software is functioning.The PL121SR radio or the PL300 module should not be replaced without verifying that these issues have been investigated. Contact your Caterpillar Technical Communicator for aid in resolving these issues.The Product Link can be configured in order to transmit diagnostics and events to the office.
